i use an r4 and this is what i did. well there isnt much to do as of setting up besides downloading rudolphs exploder then just run in once. then as long as there are gba games in there they should work. the web browsering, just launch the web browser then it should work

OK, heres what to do. Download Rudolfs GBAExploader (google it). Put all your roms in a folder called GBA in the root of your flashcard. Run GBAExploader, and select (using L and R) either PSRAM mode or NOR mode. NOR mode is slower but bigger, PSRAM is smaller but WAY faster. When you select a GBA rom, it will ask you to save SRAM to a sav file. If you havn't run a GBA rame before, press B. Then, it will ask you to load a save game. If it's a new Game, press B again. Now, after the rom has loaded, it will boot the GBA game.

After you have run the GBA game, go back in to GBAExploader and backup the SRAM to a save file, for you to load later.
